2 These Procedural STANDARDS were developed using reliable engineering principles and research plus consultation with, and information obtained from, manufacturers, users, TESTING laboratories and others having specialized experience. They are subject to revision as further experience and investigation may show is necessary or desirable. System BALANCING , which complies with these Procedural STANDARDS , will not necessarily be acceptable, if when examined and tested, it is found to have other features that impair the result intended by these STANDARDS .

3 The National Environmental BALANCING Bureau assumes no responsibility and has no liability for the application of the principles or techniques contained in these Procedural STANDARDS . Authorities considering adoption of these Procedural STANDARDS should review all Federal, State, local and contract regulations applicable to the specific installation. II FOREWORD The purpose of the NEBB Procedural STANDARDS for TESTING ADJUSTING and BALANCING of Environmental Systems is to establish a uniform and systematic set of criteria for the performance of the TESTING , ADJUSTING and BALANCING of environmental or Heating, Ventilating and Air-conditioning (HVAC) systems.

4 Today s buildings provide highly controlled indoor environments. These conditions could not exist without sophisticated mechanical systems created by a team of skilled professionals. A key member of this team is the NEBB Certified Test, Adjust, and Balance (TAB) Firm. This Seventh Edition represents a departure from past editions and is divided into two distinct Parts: STANDARDS and Procedures. These TAB procedural STANDARDS have been developed using language defined by Shall, Should, and May as it relates to the STANDARDS and procedures described in this manual.

5 It is important to note these particular words throughout this manual and how they pertain to the NEBB STANDARDS and procedures. These STANDARDS and procedures are intended as the minimum NEBB requirements that a NEBB Certified TAB Firm shall follow when performing TESTING , ADJUSTING , and BALANCING procedures. Contract documents may supercede the NEBB requirements. These TAB Procedural STANDARDS have been carefully compiled and reviewed by the NEBB Technical Committees. Part 1 STANDARDS Part 1, STANDARDS , covers the requirements for Quality Control and Compliance, Instrumentation Requirements, and TAB Reports.

6 Revised requirements for TAB instruments and reports are identified. The new report requirements allow the NEBB Certified Firm more flexibility in designing their reports by prescribing sets of information that "Shall, Should and/or May" be required to complete a TAB Report. Part 2 PROCEDURES Part 2, PROCEDURES, covers measurement procedures and the TESTING , ADJUSTING and BALANCING of both air and hydronic distribution systems. APPENDICES The Appendices include an overview of TAB Instrumentation, a Pre TAB Checklist, and a suggested TAB Specification.

7 This Seventh Edition of the TAB Procedural STANDARDS , when used by NEBB Certified TAB Firms, will assure the building owner or operator a properly balanced environmental system within design and installation limitations.
